Re: Kinematics



"The Chi-squared / dof(2) is 2.4."

Look up table gives ~9% probability of obtaining a Chi-squared greater
than 2.4. Therefore, one may reject the "assumed distribution" at the
ten % level but not the five.

bc who would also "gather" more data

Ludwik,

It may be superfluous to the pedagogical intent of your exercise, but
I would suggest that the best way to answer the question, "Was the
acceleration (reasonably) constant?" (admittedly, a question you
don't claim to be asking) is "simply" to fit the raw data directly to
a constant acceleration curve and decide whether the fit is "good."
